saber saw

The powered sabre saw is typically a larger more powerful jigsaw
and is usually referred to generically as a reciprocating
saw. The main distinction between the saber/reciprocating saw and the
jigsaw is that its overall appearance is somewhat reminiscent of a saber
sword. Its use in the hands is more typically against vertically standing
objects unlike the jigsaw which has its primary use for cutting horizontally
across surfaces. The saber saw consists of a reciprocating cutting implement,
usually a toothed blade, to chiefly cut through wood and other various materials.
Due to its large blades (relative to the jigsaw) its primary use is to slice
material handily, rather than using the traditional circular saw in the
application of building homes. It is also a handy implement when cutting
into tight crevices.

The unpowered saber saw consists of handle that grips an interchangeable
blade. It is primarily used in metal working and the building industry in
situations where the object to be cut cannot be hindered by the frame of
the hand held implement holding the blade, e.g. in metal working the hacksaw's
frame doesn't allow for cuts to be made close to the blade where a hindrance
would otherwise touch the frame. There are many similarly designed cutting
implements that have the traditional saber saw's qualities but are not referred
to as saber saws, these include the keyhole
saw, and some Japanese varieties of woodwoorking tools, e.g., the kataba
saw.
